Where are the "internet examples of Delphi 7" located?
Inside the Delphi7 installation or where? I can't find any.
By the name you write it looks to me (without having found the example) that it
is a*network* application using TCP/IP sockets or the like.
I know this is a possibility but seems to be problematic since it implies that
the communication is via the LAN. What about situations when there is no network
connection?
The IPC as described seems to use internal messaging channels on the Windows
computer it runs on and not the network...

I have found it on the Kylix installation. But I did a quick search of
Delphi NetChat and I found it immediately. It should be in the Demos
folder. Demos->Internet->NetChat. You may also download it from
Internet, where a Brazilian guy has made it available:

Yes it is a network app, but it can be used locally, just by connecting
both sides via localhost (i.e. 127.0.0.1), the loopback interface, which
can be used whenever you want to connect TCP/IP server-client on the
same machine. It's fundamental to test network apps locally before
deploying it.
Just search for "windows localhost", and you'll get the Microsoft
documentation about it:
https://learn.microsoft.com/en-us/windows/iot-core/develop-your-app/loopback
and other contributions which may be useful.
That way you'll be using tools which are widely used and tested, and not
very special ones which may fail outside a particular environment.
